Comparison of fertilizer disc granulator and rotary drum granulator

September 17, 2019 by Huaqiang Yi  

Disc granulators and rotary drum granulator are two types of fertilizer granulator machine commonly used in organic fertilizer production and NPK fertilizer production, but for those who are just beginning to prepare for fertilizer production, they do not necessarily know how to choose these two granulator, in order to make a correct choice between the disc granulation system and the drum granulation system, we now make a quantitative comparison of the working methods of the two granulators. In the same workshop, in the case of the same granulation process, process raw materials and monitoring conditions, two processes were used for simultaneous granulation, and the following conclusions were compared:

1. The capital construction investment of the two processes is roughly equal;

2. The construction space of the disc granulation process is about 10% less;

3. The physical labor of the two processes is approximately equal;

4. The power consumption of the disc granulation system is high;

5. The noise of the disc granulation system is low;

6. The disc granulator requires fewer products and less equipment;

7. Product quality, the two fertilizer granulator machine processes are not divided. From the cost of granulation, in combination with the above four items, the disc granulation system is only 2% lower than the drum granulation system. This small difference prevents us from making simple choices between the two.

According to the actual production needs, you can choose the following methods:


(1) Disc granulator has the characteristics of automatic grading, small land occupation, low cost, zero operation, and easy observation. Therefore, it can be used to guide the granulation process of a wide variety of material sizes.

(2) The rotary drum granulator has the characteristics of large production capacity, long residence time of the logistics, and simultaneous operation of various processes. The machine is most suitable for direct granulation after fermentation of organic fertilizer, saving the drying process and greatly reducing the manufacturing cost. Therefore, it is suitable for granulation of materials which are not easy to granulate, and is suitable for mass production.
